Wow, looks great. How is this different from VS Code‘s copilot?

was pretty good too, but it had taken on too much in its latest version 2.0.0. In other words, it is too unstable at the moment (but probably worth looking at again later).
1. You can configure which LLMs you want to use, whereas Copilot just supports OpenAI models. I just use Claude 3.5 for everything.
2. Chatting with the LLM can produce file edits that you can directly apply to your files. Cursor's experimental "Composer" UI lets you prompt to make changes to multiple files, and then you can apply all the changes with one click. This is way more powerful than just tab-complete or a chat interface. For example, I can prompt something like "Factor out the selected code into a new file" and it does everything properly.
3. Cursor lets you tune what's in LLM context much more precisely. You can @-mention specific files or folders, attach images, etc.
Note I have no affiliation whatsoever with Cursor, I've just really enjoyed using it. If you're interested, I wrote a blog post about my switch to Cursor here: https://www.vipshek.com/blog/cursor. My specific setup tips are at the bottom of that post.
I'd recommend just trying it, because it's hard to summarise how much it's not copilot.
As it is though, I suspect whatever model Cursor Tab is using under the hood has a fairly small context window, so the range of that "tab to move" feature ends up being pretty limited.
Overall my takeaway after months of using Cursor is that it has some really promising features but their LLM engine is too underpowered to deliver.
Hopefully that will change over the next few years. The potential is definitely there.
